Of course it was scripted. It was the most scripted thing in the world. How can this even be a question? Did the video look like gameplay in the least bit? It most definitely was not.
I'm not sure if this is sarcasm or not. So just to play it safe.... it is gameplay. Completely dynamic and not scripted.

"Glad people got to finally see some Skyrim animation in this trailer. All that dragon stuff actually happens dynamically in-game."

@OutlanderDF Yes, in-game. Only things not in-game are the shots of the wall from the previous trailer. Dragon fights are pretty epic
